Lots of people are terrified of sales.
So here’s my advice:
When you go to a sales meeting, make a sales call, or send the follow up email, adjust your perspective around the following idea: THEY need to sell YOU.
You as a person or a company should be selective about who you do business with. As much as you are there to close business and sell them, they have to be the right fit for you. Make sure they prove themselves as much as you are proving yourself.
It’s just a helpful mindset to adopt.
